VEHICLE-SEAT.

EBPECIPICATION forming part of Letters Patent No. 339,016, dated March30,1886.

Application filed December 2,1885. Serial No. 184,481. (No model.)

T aZZ whom it may concern.-

Be it known that I, GEORGE H. SAWYER, a citizen of the United States,residing at Lamoille, in the county of Bureau and State of Illinois,have invented certain new and useful Improvements in Vehicle-Seats and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a part of this specifica' tion.

This invention relates to vehicle-seats, and it has for its object toprovide the same with a yielding back to compensate for and prevent anyjolt or jar to the driver when the wheel of the vehicle strikes anobstruction,

drops into ruts, or is driven fast over rough ground; and it consists insupporting the back to the seat by spring-bars, and combining therewitha pair of coacting bars,one attached to each end of the back at one end,and the other end of such bars passing loosely through a barrelconnected with the end boards of the seat, said end being surrounded bya coilspring inclosed by the barrel, as more fully hereinafter set forthand claimed.

In the drawings, Figure l is a front view of my improved seat, and Fig.2 is an end or side view of the same. Fig. 3 is a sectional view of thecasing.

The seat proper, A, has end or side rests, B. The back 0 is connectedwith the seat by springbars D, as shown. Side arms, E, are bentelbow-shaped, and their upper ends are bent at nearly right angles tothe plane of the arms. These ends are secured to the back by clips F.Their lower ends pass through the end of and into a barrel or casing, G,extending upwardly, with a rubber washer secured inside of casing, andare surrounded by a set of coil stretch-springs, H, which are right andleft coils and are held in place by two nuts screwed on the end of thearmone each side of the end of the coils--which tighten or loosen thecoils by screwing the nuts back or forward on the arms E, when desired.

The casing or barrel G is secured to the sides B of the seat below itsupper edge, so as to be out of the way and not discomfort the rider,while at the same time the arms E will serve as a safeguard and rendermore secure the position of the occupant.

In practice, when the vehicle receives a jar orjolt, the spring-bars Dand the yielding arms E will prevent the communication of the same tothe back of the occupant of the seat, as will be manifest. lVhen theback yields, the angle or inclination of the .same with the seatchanges; consequently the upper end, 6, must have a partial rotarymovement in itsbearings; otherwise the purpose for which the device isdesigned would be defeated. The same result would be accomplished if thebarrel or casing were pivotally secured to the sides of the seat, so asto accommodate its position to the direction of the strain. In thislatter case the ends e may be rigidly secured to the back.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s-

1. The combination, with a vehicle-seat, of a back connected therewithby spring bars, and arms, one on each end of the seat, their upper endsconnected with the back, their lower ends passed through a barrelsecured to the sides of the seat below their upper edge, andcoil-springs inclosed within such barrels and surrounding the ends ofthe arms and held thereon by adjustingnnts, substantially as set forth.

2. The combination of the seat having sides, a barrel secured to eachside below its upper edge, a spiral spring located within each barrel,the back spring-bars connecting the same tothe seat, elbow-shaped armshaving their upper ends bent at nearly right angles and secured bykeepers to the back, one at each end, the lower ends of said arms beingpassed through the ends of said barrels and within the coilsprings, apacking interposed between the springs and the ends of the barrels, andnuts on the ends of the arms to adj ustably confine the springs thereon,substantially as and for the purposes set forth.

In testimony whereof I aflix my signatui e in presence of two witnesses.

GEORGE H. SAYVYER.
